Bernd Würsig is Grand Master of the Sockrifice Ceremony that has undergrad, grad, and post-grad researchers ritually burning (carried out very safely!) their most used pair of field socks during the second-in-a year Friday the 13th, which only comes once per several years.

The first Sockrifice Ceremony was held on November 13, 1998 — a year with three Friday the 13th!
